本文实例讲述了php实现的xml操作类。分享给大家供大家参考，具体如下：

new_xml('test.xml');$test->root('document');$test->append_root_node('book');$test->append_child_node('author','linage');$test->append_child_node('page',100);$test->append_child_node('money','35 RMB');$test->append_root_node_end();$test->append_root_node('book','name','The"Web"Servers');$test->append_child_node('a u t ho"r','li n a g e');$test->append_child_node('page',100);$test->append_child_node('money','35 RMB');$test->append_root_node_end();$test->display();$test->save();生成的xml结果:linage10035 RMBli n a g e10035 RMB*/class xml{var $version;var $encoding;var $start;var $end;var $filename;var $xml_document;var $root_start;var $root_end;var $rss_start;var $rss_end;function xml($ver='1.0',$encoding='GB2312'){ $this->version=""; $this->rss_start=""; $this->rss_end="";}function new_xml($filename){ $this->filename=$filename; return true;}function root($element){ $element=$this->filter($element); if(isset($this->start) and isset($this->end)){ exit("error:Only one top level element is allowed in an XML document./r/n"); }else{ $this->start="<$element>"; $this->end=""; $this->xml_document=$this->version."/n".$this->rss_start."/n".$this->start."/n"; return true; }}function append_root_node($title,$property=null,$pro_val=null){ $title=$this->filter($title); $property=$this->filter($property); $pro_val=$this->filter($pro_val); $property!=null?$pro_str=" $property=/"$pro_val/"":$property=null; $contents="<{$title}{$pro_str}>/n"; $this->xml_document.=$contents; $this->root_end=""; return true;}function append_root_node_end(){ $this->xml_document.=$this->root_end."/n"; return true;}function append_child_node($title='undefined',$contents='undefined',$property=null,$pro_val=null,$cddate=false){ isset($property)?$pro_str=" $property=/"$pro_val/"":$property=null; $title=$this->filter($title); $contents=$this->filter($contents,false); $property=$this->filter($property); $pro_val=$this->filter($pro_val); $cddate===false?$cddate=false:$cddate=true; if($cddate){ $contents="<{$title}{$pro_str}>/n"; }else{ $contents="<{$title}{$pro_str}>$contents"; } $this->xml_document.=$contents."/n"; return true;}function display(){ header("Content-type: text/xml"); $xml=$this->xml_document.$this->end."/n".$this->rss_end; echo $xml; //return true;}function filter($sring,$replace_null=true){ $filter[]='"'; $filter[]="//"; $filter[]="/n"; $filter[]="/r"; $filter[]="/t"; $replace_null===true?$filter[]=" ":$replace_null=false; foreach ($filter as $val){ $sring=str_replace($val,'',$sring); } return $sring;}function encode(){ //you can add the convert encode function here or add other class to do that}function save(){ $this->xml_document=$this->xml_document.$this->end."/n".$this->rss_end; $handle=fopen($this->filename,'wb+'); $result=fwrite($handle,$this->xml_document); fclose($handle); if($result){ return true; }else{ echo "error:can't write to files,maybe the access denied.try to chmod 777 the directory?"; return false; }}}
